bination and arrangement of parts, greatlyfacilitating the loosening andremoval of foreign matter from the hair and further aid- 10 ing in thedistribution of the oil from the' scalp to the hair.

Other objects, features, and advantages will hereinafter appear.

In the drawings forming a part of this specification Fig. 1 is a}perspective view of such a comb embodying t e invention;

Fig. 2 is a fragmentary view ofthe side of a blank from which such acomb may be formed;

Fig. 3 is a fragmentary view of a partially formed comb;

, Fig. 4 is an end view of a finished comb;

Fig. 5 is a fragmentary plan view illustratin the action of the comb onthe hair;

ig. 6 is'a side view of a single tooth; and

Fig. 7 is a modification of a single tooth.

A preferred form of construction of such a comb is illustrated in thedrawings and comprises a handle or back 35 integrally formed with teeth31 having pointed ends 37, body portions 38 of prismatic form, andcurved base portions 39. These curved base ortions form one continuousrow at their uncture 40 with the handle or back and pro'ect alternatelyand oppositely therefrom wit the furthermost parts projecting in thesame general direction.

The points and body portions of the teeth are in spaced relation and arealternately arranged in two longitudinal rows, with said points and bodyportions staggered with respect to eachother. In this respect, it is tobe noted that the interdental spaces 33 of each row are directl op ositethe teeth of the other row, and t at t e longitudinal. rows are spacedapart, forming the longitudinal space 32. The effect-of this arrangementis to provide tortuous transverse passageways for the hair, asillustrated in Fig. 5.

In the application of the comb to the hair preparatory to its beingdrawn therethrough, the oints 37 act as wedges, the bodies 38 as gui esto the interdental spaces 33 and therein separate the hair, see Fig. 5,into a number of strands 42, 43, and44 in one longitudinal row (1-6, andthese said strands are divided by the teeth of the other longitudinalrow c l into smaller strands 45, 45', 46, and 46, and in the'interdentalspaces of the said row cd are the strands 47 and 48 formed from thestrands 45 and 45 and 46 and 46, respectively.

The comb in motion relative to the strands of hair performs the novelfunction of causing the strands to pass through the interdental spaces33 in one longitudinal row, as 4 a/.b, diagonally through thelongitudinal space 32 and out the interdental spaces 33 of the adjacentlongitudinal row, as od, causing the strands to be drawn against thesides of the bodies 38 of the teeth 31 in a doublecurve formation. Thesetortuous transverse passageways'cause the strands to be pulled againstthe sides of said bodies and to ride over the edges or ridges 41, whichdevelops a friction to the passin' strands, causing said strands to havea ten ency to.flatten themselves against said bodies and edges orridges. This flattening of the strands brings a great portion ofthe'hair in contact with the edges or ridges 41, giving the hair ascrapin treatment when the comb is in motion. fiy this scrapingtreatment, the foreign matter which may be attached to the hair isloosened and carried to the ends of the hair and removed. Incidental tothis scraping treatment, the oil from the scalp is carried along and,because of its nature, becomes distributed along the hairwit-hbeneficial result.

A modification of the tooth as illustrated in Fig. 6 is illustrated inFig. 7. This tooth has a columnar twist, the edges or ridges 41 arespirally arranged upon the body of the tooth and, where it is desired,may be used in this form of comb for the purpose of lessening thetension to the passlng strands and increasing the length of the ed es orrid es 41 in touch with the strands 0 hair.

he comb may be constructed of any madescribed, the process of formingterial commonly used for such pu ose but is preferably constructedofsuitab 0 metal, such as aluminum, by the following described method:

First, from suitable sheet material, a blank is formed, see Fig. 2having one edge serrated to correspond to the points 7 of t e teeth 31,the opposite edge to correspond to the outline of the back or handle 35,and the ends to corres 0nd to the outer edges of the end teeth of thecomb;

Second, the blank as shown in Fig. 2. is

' cut from the oints of indentation 36 on the a series of parallel lines34, see ig. 3, b cuts of equal length, orming a number of stripsattached to the back 35, each strip constituting a whole tooth 31, withthe ed es or ridges 41 formed incidentally by sai ting;

Third, referring to Figs. 3, 4, and 6, the ortion of the strips or teeth31 adjacent the back or handle 35 are bent into a curved formationbranching alternately and o positel from their juncture with said bac orhan 1e, arranging the bodies of the teeth into their respective rows,and thereby providing the interdental spaces and the longitudinal spacewhich combined provide t e tortuous transverse passageways,

While I have shown and described a preferred and specific embodiment ofthe invention, I do not limit the construction to the exact detailsshown but may resort to such changes and modifications as occasion mayrequire and as may come within .the spirit and scope of the appendedclaims.

I claim:

1. In the construction of a comb of the class a blank from sheetmaterial, cutting the blank to form strips of tooth form attached to theback or handle thereof and bending an inner part of each of said stripsto form curved base portions to position the teeth in rows and toprovide tortuous transverse passageways.

.2. In the construction of a comb of the class described, the process offorming a blank having one edge serrated to correspond to" the points ofthe teeth, the opfposite edge to correspond to the outer edge 0 the backor handle, and the endsto correspondtothe outeredges of the end teeth;cutting the said blank from the points of indentation by a number ofparallel cuts of adopted length, made intermediate the ends to formstrips of tooth form, attached 1 to the back or handle thereof; andbending an inner part ofeach of the said strips adjacent the back orhandle thereof to form curved base portions to position the teeth inrows, and to provide tortuous transverse passageways.

3. A comb comprising a back portion; a

. plurality of teeth projecting alternately and oppositely from saidback portion with the operative portions of each of said teethprocutjecting in the same general direction with the points and bodyportions of said teeth arranged in two spaced longitudinal rows.

4. A comb having two rows of teeth in spaced relation, the operativeportions of the teeth of each ofsaid rows arran ed in staggeredformation with respect to t e operative portions of the teeth of theother row.

5. A comb having a plurality of teeth projecting in the same generaldirection, the points and body portions of alternate of said teetharranged in two longitudinal rows with longitudinal s ace between saidrows.

6. A comb aving two rowsof teeth in spaced relation, the operativeportions of the teeth being arranged to provide tortuous transversepassageways. j

7. A comb having a plurality of teeth arranged in spaced relation toprovide tortuous transverse passageways.

8. A comb comprising a back portion, a plurality of teeth havinglongitudinalscra ing ridges disposed lengthwise their bo y portions, andcurved baseportions projecting alternately and oppositely from saidback, the said body portions being arranged in two longitudinal rows inspaced relation, having transverse passageways between the teeth, andthe said ridges p110 ecting into the transverse passageways.

9. A comb having a plurality of teeth arranged in spaced relation toprovide tortuous transverse passageways, said teeth being provided withlongitudinal scraping ridges projecting into said passageways.

In witness that I claim the foregoing as my invention, I afiix mysignature this 28th day of January, 1929.
